Jonathan Walden’s obituary states that his parents died when he was young and he converted to the Baptist faith, shortly before moving to Ohio. It gives no other indication to his family.
The earliest records located for Jonathan show that he married Sarah Millikin in Jackson County, Ohio in 1832 (Ohio, County Marriage Records, 1774-1993 | ancestry.com) and that he lived in Liberty Township, Jackson County, Ohio with his wife and five children in 1840 (1840 census | ancestry.com).
Records for Lewis Walden
Also living in Liberty Township, is Lewis Walden. He is roughly the same age as Jonathan, with his age recorded in the census in the same age bracket: 40-49. His household appears to contain two family groups. He is living near John Milligan, the brother-in-law of Jonathan Walden.
| Age Range | Female | Male |
|---|---|---|
| 40-49 | 1 | 1 |
| 30-39 | 0 | 1 |
| 5-9 | 2 | |
| under 5 | 1 |
The similar age bracket and geographical proximity suggests the likelihood that Lewis Walden is the brother of Jonathan.
In 1850, Lewis has 100 acres (US Non Population Schedule) and the farm is valued at $1200. He has two horses, five milk cows, six other cattle, 24 sheep, and ten pigs. He also has a sizable amount of butter and wool. He is living with his wife, Mary A Walden and James McCormic (age 20), who is most likely one of the males listed in the 1840 census. He is listed as a teacher who was born in Ohio. Lewis Walden, like Jonathan, was born in Virginia, supporting the theory that Lewis came with Jonathan from Campbell County, Virginia.

Lewis married Mary McCormic in Scioto County, Ohio, in 1834. This suggests that the 30-39 male in the household was a relative of Mary rather than Lewis, and that James was the son of the relative.
